Ölkontrollsystem für eine Presse

摘要

A dynamic oil control mechanism 46, 47, 50 for a press (10, Fig 1) including a vacuum inducing ejector (60 Fig 3) or jet-pump connected to conduit 50 to vacuum oil leaking from about an oil seal 40. The oil seal is located around the drive piston 34 on the press slide to prevent oil migration from the press crown 12 to the die area or slide of the press. A drain port 47 is located about the housing 46 in which the drive piston reciprocates. The ejector maintains a low pressure area within the drain port to pull oil leaking from the seal into the drain port and away from the drive piston. The vacuumed oil is then transferred to an oil reservoir. <IMAGE>
